ANTIVFRICTION-BEABJNQ,V

SPECIFICATION forming part of Letters Patent No. 623,113, dated April11, 1899. Application filed October 17,1898. Serial No 693fl95. (Nomodel.)

To all whom it may concern:

Be it known that I, JONATHAN WATERBURY, a citizen of the United States,residing at Brooklyn, in the city of New York, county of Kings, andState of New York, have invented a new and useful Antifriction-Bearing,of which the following is a specification.

This invention relates to bearings for shafts, &c., and has for itsobject to reduce the friction in the journals. I attain this object bythe mechanism-illustrated in the accompany ing drawings, in which Figure1 is a view of a shaft with a sectional view of my invention appliedthereto. Fig. 2 is a plan view of myimproved antifriction-bearing withthe cone removed, and Fig. 3 is a modification thereof.

In the drawings the separate parts are indicated by numerals ofreference, and in the practice of my invention I provide a plate 5,

which I mount loosely in the cup 6, which is mounted in the hub orbracket of a bicycle. in a manner well known and therefore not describedin this connection. 7 represents the shaft, and the plate 5 is providedwith a central opening 8, which is greater in diameter than that of theshaft 7, and with radial arms 9, to each of which is secured a shortshaft 10, having a head 11, and on the shaft 10 I mount a small roller12. The plate 5 is made of such a size that when placed in the cup 6 theperipheries of the rollers 12 will not come in contact with the innerwall of the cup; but this feature is not essential.

Between each of the radial arms 9 I mount a bearing-ball 18, which ballsare so proportioned in size that they will fit loosely between therollers 12, and the diameter of the balls is greater than the diameterof the rollers.

On the shaft 7 I mount a cone 14, which bears against the balls, asshown at 15, whereby the shaft 7 is supported by the balls 13 and nopart of it comes in contact with any part of the cup 6. used in bicycleconstruction, and consists of an annular band and an inwardly-directedsaid cup, so that the bearing-balls have but three points of contactin'the raceway-via,

against the inner wall of the annular band of the cup, against theinwardly-directed fiange,

The cup 6 is the ordinary cup and against the cone. It will thus be seenthat I have adapted my device to the most improved method of forming araceway without sacrificing any of the essential features thereof.

The plain side of the plate 5 rotates in contact with theinwardly-directed flange of the cup; but as the rollers 12, which aremounted .the balls alone, and therefore always with the balls, so thatthere is no friction between the balls and rollers which would be in anywise appreciable. Another advantage is that the balls are always kept atequidistant points,

so the cone is supported and held at every point,while with balls aloneit is impossible to place them so close together in the cup but whatthere will be a slight space left between them at the upper side of thecup when in use, thereby causing a slight play of the axle.

In Fig. 3 I have shown a slight modification in-which the radial arms 9are reduced in number and made larger, and two rollers 12 are mountedupon each arm. Apossible advantage of this construction lies in the factthat fewer bearing-balls 13 are required and the adjacent balls do notcome in contact with the'same roller, so that if for any reason theballs did not rotate 'in unison there would be no friction between theballs and rollers.

While I have described my invention as being applicable toantifriction-bearings in connection with shafts, I do not wish toconfine myself to that use, as the bearing is applicable to other uses,and I claim the right to make any changes or alterations that fairlycome within the scope of my invention.

Having described my invention, What I claim as new, and desire to secureby Letters Patent, is-- 1. In an antifric-tion-bearing, a cup consistingof an annular band and an inwardlydirected flange, a cone mounted on theaxle in the open end of said cup, bearing-balls mounted between said cupand said cone, a

plate mounted in said cup and bearing With 4 plate mounted in said cupand bearing Withits plain side against the flange thereof, said platebeing provided Withradial arms, stubshafts on said radial arms on theside opposite to said flange, and rollers mounted on said stub-shafts,said bearing-balls being separated by said rollers, and being greater indiameter than said rollers, substantially as and for the. purposedescribed.

In testimony that I claim the above I have hereunto affixed my signaturein the presence of two subscribing Witnesses.

JONATHAN \VATERBURY.
